My husband thinks our small electric (60 Hz, 1500 watt) convection/toaster oven is evil. He thinks I should toss it and only use our conventional gas oven when the microwave is inappropriate. If someone can quantify the difference between baking something like a single loaf of pound cake in these types of ovens, I will discard the convection/toaster oven if it has a bigger carbon footprint and/or higher energy cost. Forgive me if this is a frequently asked question. I am a newbie.

Here's a quick test: close the kitchen doors and see which one heats up the room more. I bet it's the gas oven by far. Combustion appliances need air flow, while the electric toaster oven, though poorly insulated, loses heat only through its walls, and it has a small surface area to boot.

Electricity is 2-3 times more expensive than gas, but still, I bet the difference between the two ovens is on that order.

My gas oven is evil, and I do much more baking in the winter than the summer.
